Will 13" Props fit on Stock AD8 Heavy Lift frame with 410mm booms?

Hey guys,

Before I start this build. Will 13" Props fit on Stock AD8 Heavy Lift frame with 410mm booms? All Documents and advertisements say yes, However, It just seems that they are to short. Does anyone have a deffinant answer to this?

Thanks,

Patrick

Someone else might be able to help sooner, but if you can tell me motor to motor dimension, I can draw it to scale and tell you if it will fit or not.

Cheers,

Gunter.
 

Measurement from Center motor shaft to the Center of the next (to the right ot left) Motor shaft is 32 3/4 inches. Is that the correct info needed?

Not sure...what I need is the distance from the center of the motor shaft, across the center plates, to the motor shaft on the opposite side. It sounds like it is the correct dimension though, that's about 815mm which seems about right.

Just let me know if that is how you measured it.

I have drawn it up - if you have measured it like I think you did, then 13" props won't fit. 12" do fit, with 13mm distance between tips.

13" will not fit the old frames. The old frames are still being sold because reseller want to get rid of the first....
New ad frames have 430 booms wich will support 13" they say.

What motors will you use is the question... Ecalc it first.

Good luck

I just bought an AD-8HLE and was not sure which props would work best and, since the Droidworx spec sheet indicates either 12 or 13" props with 430mm booms needed for 14" props, I ordered two sets of 12" and two sets of 13".

The 13" do NOT fit 410mm booms.

Then I got stung by AltiGator who charged me a restocking fee because I had not notified them within a week that I wished to return them. Who the hell looks at the props until the rest is done and who the hell ever finishes building within a week after waiting for all the parts to arrive from different places because nobody seems to stock EVERYTHING at the same time.

And anyway, it was Droidworx' disorganised fault, not mine. I'll bet Macgrafs will have something to say about THAT conspiracy.

It annoys me now that I do not have the choice to try the 13" because I am finding the AD-8 puffs a bit when carrying the 5D.

Having struggled with assembling and configuring the stupid, fiddleass Bluetooth wireless data link thingies I was pleasantly surprised to discover they actually work. So, the first thing was to check in-flight BL temperatures. They reached a whopping 95°C when carrying the 5D with a miserable flight time of six minutes.

So, my solution is to leave the 5D for the big gasser heli (or sell it) and stick a NEX-5 on the AD-8 to lower BL temps and recover a few minutes of air time.
